Joppa

Joppa is an unincorporated community in Harford County, Maryland. It was founded in 1707 as a British settlement on the Gunpowder River, and it was named for the Biblical city of Jaffa. Joppa was used as a port of entry for the tobacco trade during the 18th century, but the silting of the town's harbor and disease outbreaks led to a rapid decline in population as most of its residents moved to Baltimore.
